OF SAID WILLIAM DBAFT-RIGGING.

I specification of Letters Patent. Application and Kay 2a, 1908. Serialno. samba- Pa'tented May '7 1912.

To all whom it may concern:

Be it known that I, WILLIAM P. Barranoonr, a citizen of the UnitedStates, and a resident of Davenport, in the countyof Scott and State of-Iowa, have invented certain new; and useful Improvements in Draft-Riggings, of,which' the following is a clear, full, and exactdescription.

My invention relates to draft-rig ing, which is particularly applicableto ra' way cars, the underframes of which comprise a single I-beamcenter-sill.

The object of my invention is to support the draft-rigging in a suitableopening in the ends of a single rolled beam of the center-sill, in suchmanner that the strain of the stress and pull can be communicated tosaid center-sill in such manner that said strain is communicated to allparts of the same.

A further object is to provide an integral column connecting the web ofthe bifurcated ends of the single center-sill, above and below thedraft-rigging, through which the pulling strain of the draft-rigging iscommunicated to the underframe of the car. And a further object is toseparate the forward part of the draft-rigging from the part in whichthe sprin are housed and to to give it an in e- .ndent longitudinalmovement extending it forward of the aforesaid web column. And a stillfurther object is to'connect the rear portions of the draw-bar with thehousing for the springs, by links, the forward ends of which areconstructed to permit of a limited butting movement of the draw-bar ofthe car-coupler before receiving the bufiing impact and communicatingthe same directly to said housing. This I accom lish by the meanshereinafter fully descri ed and as particularly pointed out in theclaims.

In the drawings: Figure 1 shows a broken away end portion of a singlecenter-sill, having its extremity secured to the end-sill of the car andhaving my improvements applied thereto. Fig. 2 is a longitudinalhorizontal section taken on dotted line 2-2, Fig. 1. Fig. 3 is atransverse section taken on dotted line 33, Fig. 2. Fig. 4 is a peredgespective view of the rear broken away end of the draw-bar, drawn to a,slightly larger scale. Fig. 5 is a perspective view of thebutting-block.

In the drawings A represents a single I-beam center-sill, the ends ofwhich are provided with bifurcations a, a', the uppermost of which issecured, by means of suitable corner castings b, to the end-sill B ofthe car. This end-sill'is shown to be constructed of a channel-beamtheflanges of which project inward, and itis provided, in the verticalplane of the couplln C, with a cast metal frame 0, that surroun s the ojening through which said coupler extends. e lower horizontal portion ofsaid frame 0 is flan d rearwardly, at about the oente'rof-wi tn thereofto form a seat d, u on which the lower flange of the lower rests, and issecured byrivets or otherwise.

Coupling 0 extends longitudinally. back ifurcations a" into thelongitudinally elongated slot or.

space a separating the bifurcations a, a, and its rear end terminatesnear the crotch of'the same. This crotclris formed by a vertical columnD, consisting" of an integral portion of the web of-the. center-sill,and reinforcing plates e riveted to .eachside thereof, and itconstitutes the dividing medium between the'longitudinally extendmgopening E in which parts of the draft-rigging are located and the spacebetween said b1f11 1- cations or and a. Opening E is, preferably, inalinementwith and is greater in height than s ace a,-and the verticaledge of the web 0 the center-sill formin its rear end is reinforced andstrengthene by means of peculiarly shaped cast-plates F, which areriveted thereto, substantially as shown. The ofthese plates in the sametransverse plane as the adjacent end of opening E is verticaL-whereasthe opposite edge, pre erably, describes a semi-circle, and the entireouter edgesv of said plates-are flanged laterally, substantially asshown. The rear portion of the edges of'the space a between thebifurcations and the upperand lower edges of opening E are reinforced bya U-shaped angle-iron strip G, the end of which farthest from'thecoupler is bent and extends around 't'urngagends .of brackets 5,

Asthus constructed the openings in the single arolled metal amconstituting the centersill,,"for insects iron of'the draft-rigging, donot Weakenthe end of saidcenter-sill, but addto its strength, and itsability to receive 1 and'resist the stress of the pulling and pushg. oedr' z er gg gr j ,Q'Ihe; draft-rigging comprises a housing-2 for thesprings 3, that consists of a tubular casing whose-, rearg tend 4 isclosed and nor. jmall yib ars against the forward flanged end '20 fhereinforcing plates H, and whose other .isjopen;..- Thishousing isplaced in open- -E,*a'nd 'retained'therein by the upi that are secured--ets aor' boltsto the vertical flanges of I gle iron binding strips,below open- The length of housing 2 is less than opening li ands itsforward end does not 'yreach; -:o:lu' n IZD, and 'in'the space between'said coluinn 'and' the housing, a buflingblock'tijis placed,- :thatconsists of truncated cone-shaped casing, i jend'is solidg and which, infront of this rear "solidportion;is provided with a' vertigil slot-7,.thatzextnds to and through its forward endi ='l his -slot- 7 is ofsutfiient width toenable the forward portions of the resulting divisionsoffthe blockto pass forward on each 'side' of column D.

but greater in length than the width of the key, the ends of whichextend through said openings. 7 v

The springs 3 are located in the rear portion of the housing 2, and havetheir rear ends bear against the closed end, 4, of the same. The forwardends of said springs, however, bear forward against a followerplate 14,within said housing the normal position of which is in a transverseplane slightly forward of the center of trunnions 11. The rear end ofthe bufler-block 6 communicates its movement to said followerplate bymeans of one or more eccentrically journaled rolling members 15, theconstruction of which it is unnecessary to dwell on as they constitutepart of a well known type of draft rigging now extensively in use.

In operation, when a pushing motion is imparted to the coupler it movesto the rear independently of the links 12 for a. short and, through themedium of the buffer-block and the rolling members 15-, 15, slightlycompresses the springs 3, which latter neutralize the shock and impartthe strain through the rear end of opening E to-the center-sill untilthe ends of the key come in contact with the rear end of elongatedopenings'13 of the links 12, Whereupon the bufling strain is imparteddirect to the housing of the springs'and, through it to. thecenter-sill. When the draw-bar is subjected to a pulling strain, the key10, through the medium of links 12 draws the housing forward andcompresses springs 3 against the follower-plate 14, members 15, thebuffing-block 6, and the column D, until the limit of the forwardcompression of the springs is reached, or until said springs compresssufficient to resist the pulling strain. Thus it will be seen that thepulling strain is imparted to theccnter-sill and, through it, to theunderframe of the car, through the medium of the colmn D, and thebufling or pushing strain, which is much greater than the pullingstrain, isv imparted to the center-sill through the rear end of openingEand' the plates reinforcing the same to the center-sill.
